What each part of the prompt does
- Benefit first, spec kept
- Each bullet opens with what the buyer gets and ends with the exact number or material. Shoppers who skim get the benefit, and shoppers who compare still find the spec on the same line.
- Buyer questions as FAQ
- Asking for the three questions a buyer most likely has turns common doubts about size, care or delivery into answers on the page, before they become support emails or returns.
- Missing info list
- Instead of letting the model guess a battery life or a fabric weight, the prompt asks it to list missing facts. You get a checklist of what to add, and nothing false goes live.
- Banned claims
- Words such as "best" and "guaranteed" can break marketplace rules and consumer law in some countries. The prompt allows them only when they are in your facts.

If the result isn't right
- Paste two or three real customer questions from your inbox into [SPECS] and the FAQ will answer the questions people actually ask.
- For a range of similar products, run the prompt once, then reuse the output as an example so every page keeps the same shape.
- If the copy sounds generic, make [DIFFERENCE] more concrete: a material, a process, a test you ran, a person who makes it.
